Hi
What if i use xferloop to get data from camera in Hsync active low( idle state- not included data),
What happen in windows application?
And what is best way to use xferloop in above circumstance?
Show LessCypress Semiconductor introduced a single-chip solution that integrates a wireless radio with touch-sensing circuitry for wireless mice, trackpads, remote controls, presenter tools, and other Human Interface Devices (HIDs). The new PRoC™-UI (Programmable Radio-on-a-Chip–User Interface) solution combines 2.4-GHz proprietary WirelessUSB™-NL Radio with Cypress’s CapSense® and Automotive Multitouch capacitive touch technologies. This combination enables user interface functionality in wireless devices, including gestures supported by the upcoming Windows 8 applications.

Show Less1)Hardware enviroment
Our board use CY7C68013A as synchronouse slave fifo, and a fpga as master.
CY7C68013A's CLKOUT at 12MHz, and FPGA's PLL use as input, output 40Mhz as CY7C68013A's IFCLK.
EEPROM is blank.
2)firmware and modification
use Cypress Suite USB 3.4.7\Firmware\Bulkloop example, and only modify BulkLoop.c as follow:
// CPUCS = ((CPUCS & ~bmCLKSPD) | bmCLKSPD1) ;
// CPUCS = (CPUCS & ~bmCLKSPD) |bmCLKSPD0; //24MHz
CPUCS = CPUCS & ~bmCLKSPD ; //12MHz CLKOUT
// set the slave FIFO interface to 48MHz
//IFCONFIG |= 0x40;
IFCONFIG = 0x03; //slave fifo, sync, external

I was wondering if it would be possible to parse a script (.spt) file, and if so, how to go about doing it.
We need to load firmware through non-Windows based methods. Unfortunately we have, over the years, lost track of the original .hex file(s) that were used to create a script file.
Thank you for your help.

if i use wordwide =1 in slavefifo mode, what am i do for read in windwos application program?
i usually use like below in wordwide=0,
if (USBDevice->BulkInEndPt)
USBDevice->BulkInEndPt->XferData(buf, length);
buf have [512] array and length is 512.
but, if i use wordwide =1, what am i setting value for buf array count and length value ?

In Fx2lp, if i use SLAVEFIFO mode,
What is different (bandwidth / speed )point in wordwide=1 and wordwide=0?
i know wordwide=1 is [15:0] 16bit mode. but i dont know.
if i use wordwide =1 in slavefifo mode, is bps (bits per second) is almost same in wordwide=0?
Then, wordwide=1 have actually total high bandwidth and fast bps than wordwide=0. ins't it ?
